+# Ghaymah SRE Project
 
+This repository contains a full set of SRE and DevOps deliverables for the Ghaymah platform. It includes a health-monitoring web app, a containerized dashboard, an incident postmortem, CI/CD guidance, and a high-traffic architecture design.
+
+## Project Overview
+
+The project is organized into five main parts:
+
+- Q1: API health monitoring app and dashboard
+- Q2: Incident postmortem and resilience recommendations
+- Q3-CICD: CI/CD workflow and deployment strategy
+- Q4: High-traffic architecture design for 15,000 RPS
+- Q5: Containerized monitoring service for uptime and SSL checks

+## What Each Part Includes
+
+### Q1 — API Health Monitor and Dashboard
+This section provides a lightweight web service that exposes a health endpoint and serves a dashboard for monitoring service status, response time, and request count.
+
+Key files:
+- [Q1/server.js](Q1/server.js)
+- [Q1/monitor.sh](Q1/monitor.sh)
+- [Q1/Dashboard/index.html](Q1/Dashboard/index.html)
+
+### Q2 — Incident Postmortem
+This section documents a major outage caused by memory exhaustion and proposes mitigation strategies such as autoscaling, pagination, and observability improvements.
+
+Key file:
+- [Q2/readme,md](Q2/readme,md)
+
+### Q3-CICD — Continuous Integration and Deployment
+This section outlines the CI/CD workflow for automating build, test, and deployment processes for the platform.
+
+Key files:
+- [Q3-CICD/workflow.yml](Q3-CICD/workflow.yml)
+- [Q3-CICD/README.md](Q3-CICD/README.md)
+
+### Q4 — High-Traffic Architecture Design
+This section explains how to design a scalable architecture for handling 15,000 requests per second, covering load balancing, caching, database replication, and storage planning.
+
+Key files:
+- [Q4/README.md](Q4/README.md)
+- [Q4/GhaymahAPI.png](Q4/GhaymahAPI.png)
+
+### Q5 — Containerized Monitoring Service
+This section contains a Dockerized monitoring solution that checks uptime, latency, SSL expiry, and dashboard availability using a simple Python script.
+
+Key files:
+- [Q5/Dockerfile](Q5/Dockerfile)
+- [Q5/monitor.py](Q5/monitor.py)
+- [Q5/Entrypoint.sh](Q5/Entrypoint.sh)
+
+## How to Use This Repository
+
+1. Review the documentation in each folder.
+2. Run the applications locally as described in their own README files.
+3. Use the CI/CD workflow from Q3-CICD for deployment automation.
+4. Reference Q4 for the large-scale architecture approach.
+5. Use Q5 as a container-based monitoring example.
+
+## Technologies Used
+
+- Node.js / Express
+- Python
+- Docker
+- HTML / CSS / JavaScript
+- GitHub Actions workflow-based CI/CD
+
+## Summary
+
+This project demonstrates a practical SRE approach covering monitoring, incident response, automation, scalability, and container-based operations for a production-style platform.
